Cryopreservation of human spermatozoa—introduced in the 1960's—has been recognized as an efficient procedure for management of male fertility before therapy for malignant diseases, vasectomy or surgical infertility treatments, to store donor and partner spermatozoa before assisted reproduction treatments and to ensure the recovery of a small number of spermatozoa in severe male factor infertility. 

Freezing your sperm and embryos is very common now. The process of freezing them is called vitrification. It appears that all can be frozen successfully for an indefinite period of time with no harm to them or any pregnancy that results from them. There are no increased risks of genetic problems in children born from frozen embryos or sperm. These children appear to be as normal as children who are conceived naturally.

Patients who choose to freeze their sperm are those who would like to have their sperm available for use later in situations where they are concerned that they may no longer be able to produce sperm. For patients that travel a lot and would not be available to provide a semen sample when required during a treatment cycle, may wish to freeze sperm so that sperm is available when needed.

Embryos can also be frozen. These embryos have been created during an IVF cycle. It is very common to freeze excess embryos after an IVF cycle at RCC Fertility. There appears to be very little if no harm at all to embryos with the vitrification freezing process.
